Hattrick78, I believe the biggest problem that occurs when an engine is over filled is "Foaming" of the oil. Caused by the crank shaft coming in contact with the oil and splashing it around in the crank case. I'm not familiar with the inside of our motors, but I would presume since our cars were designed with a "sporting nature" in mind, that it probably has baffles in the oil pan to help prevent the oil from sloshing around during spirited driving. This would help prevent much, if any oil coming in contact with the crank. Plus the oil pick-up should be deep enough in the pan to help prevent any "foam" from actually being sucked into the oiling system.

28 years ago my best friend and I took a cross country trip in his 1975 280Z that he purchased brand new. Since we were taking his car, the least I could do was to change his oil for him before we left. Upon doing so, I retrieved 8 1/2 qts. from his oil pan (where there should have been 5). It seems that at his last oil change someone over filled it, and he had been driving around for over 3,000 miles with it that way.
Well, we made our trip with out any problems, and with about 76,000 miles on it, he still owns it to this day. I hope that helps to ease some of your concern.
But to be on the safe side, since it registered on your dash board read out that it was hi, that means it would show up on your dealers scopes if you should ever have any problems, so you should get it documented. That way your dealer would know it wasn't your fault, but another Chrysler dealers mistake.
